Suggested solution:
1. Don't continue to light the gas stove after it is found that it won't catch fire. First, close the main valve of the gas stove to ensure safety.
2. Under the condition of ensuring safety, thoroughly clean the stains on the gas stove, pay special attention to cleaning the position near the probe and switch, and disassemble the parts for cleaning if necessary.
3. Check whether the battery is flooded. If the battery is flooded, you need to disassemble the battery, wipe off the water stains on the battery and put it in to see if it can be used. If it can be used, try to open the main valve for ignition. If it can find fire or sparks, it means that the battery is ok, otherwise it needs to be replaced with a new battery.
4. Check whether the stove eyes are blocked by soup. If the blockage is found, clean it with a rag in time.
5. If there is nothing wrong with the battery, but it won't catch fire, it means there is something wrong with the probe. There are two probes on the top of the stove. If there is soup stain during inspection, dry it and try to light it. If you miss, try again with a lighter. If the lighter can light, it means that the ignition needle is stuck in the soup, and we can wipe it with sandpaper.
6. If the above methods are ineffective, it may be that the solenoid valve is short-circuited, and professional maintenance personnel need to be invited to repair it.
